SPECIFICATION forming part of Letters Patent No. 547,176, dated October1, 1895.

Application tiled July 8, 1895. SerialrNo. 555,181. (No model.)

To @ZZ whom it may concern.:

Be it known that I, GEORGE R. MOON, a citt.

zen of the United States, residing at Columbus, in the county ofFranklin'and State of Ohio, have invented a certainnew and usefulImprovement in Cooking-Ovens, of which the following is a specification.

My invention relates to the improvement of cooking -ovens, and hasparticular relation to the improvement of that form of oven set forth inmy former Letters Patent, No. 415,649, granted under date of November19, 1889.

The objects of my present invention are to simplify the construction ofthe oven and thereby reduce the cost of manufacture of the same, toprovide improved means for equalizing the distribution or radiation ofheat throughout the oven, and to produce other improvements in detailsof construction, which will be more fully pointed out hereinafter.

These objects I accomplish in the manner illustrated in the accompanyingdrawings, in which-m- Figure 1 is a front elevation of my improvedcooker, showing for the sake of clearness a portion of the front wallthereof broken away. Fig. 2 is a central vertical section of the same online a: a: of Fig. 1. Fig 3 is a detail view in perspective of the heatdistributer or equalizing detlector, and Fig. 4 is a central verticalsection taken at right angles with the view shown in Fig. 2.

Similar letters referto similar parts throughout the several views.

In the construction of my improved oven I employ the external casing a,of sheet metal or other similar material, the latter being provided onits forward side with a doorway a and door d2, adapted to close thesame.

b represents an internal casing, which extends from the back to thefront of said eX- ternal casin g and results in forming, as shown in thedrawings, vertical side chambers b', which communicate at their upperends through the medium of atop chamber bwhich is between said internaland external casing, as shown. b3 represents openings, which are formedat suitable intervals in the wall of the internal casing b, and whichserve to provide means of communication between the interiors of saidcasings l) and a.

In the construction of my improved heatequalizer I provide an angulardeflectOr-plate c, the wings of which are arranged, as shown in thedrawings, to form conjoint-ly an obtuse angle, and the outer edgeportions of said wings are formed with upturned side flanges c', thelatter being hooked into engagement, as indicated in the drawings at c2,with the downturned side hooks or hook-liangcs d of a horizontal top orcover plate d. The plate d is of greater lengththan the plate c and hasits upturned ends d2 supported on oppositely-located brackets e on theinner sides of the casing b. The ends of the plate d are removably heldin position on said brackets by means of spring-strips f, the lower endsof which are secured to the inner walls of the inner casing and theupper end portions of which are'sprung Outward and adapted to engage, asshown, with the upturned edges of said plate ends. 'y 4For the purposehereinafter described I provide betweenthe plates d and c a series ofequaliaing-plates connected with and supported from each other. Theseequalizing plates, which are indicated at g, g', and g2, respectively,consist of parallel horizontallyarranged plates, which are provided withupturned ends, such as are indicated at g3, and said plates graduallydecrease in width from the uppermost plate downward. The upturned endsof the equalizer-plate g are secured, as shown in the drawings, to theunder side of the plate d', while the corresponding ends of the plates gand g2 are secured, respectively, to the ends of the plates g and g',the bodies of said plates being separated, as shown in the drawings.

From the arrangement of the equalizingplates which I have describedherein it will readily be seen that the narrower plate g3 is broughtimmediately above the apex or meeting-point of thel wings of thedetlecto'r-plate. As is common in this class of ovens, my improved ovenis adapted to be supportedcentrally over the burner on a gasoline orother stove or heating contrivance, and in order to support said ovenslightly above the stove-top, and consequently above the burner cover orIOO granting, I provide the under side of my irnproved oven withparallel ribs or cleats t', the lower edges of which are adapted to reston the stove-top.

In utilizing my improved oven the heat from a stove-burner is impartedmost directly to the apex or ridge of the angular deiectorplate c and isspread therefrom up each of the inclined wings of said plate to thesides of the oven. Although the heat thus imparted to saiddeliector-plate is greater at its first point of contact, it will beobserved that at this point the heat will meet with the resistance ofall of the equalizing-plates in addition tothe plate d. Owing to theaddition in width and substantially-pyramid arrangement of theequalizing-plates, it is obvious that this resistance to the heat isgreatly decreased as the intensity of the heat is decreased by spreadingfrom its first point of contact. In this manner it is evident that asubstantially-equal distribution of the heat over the plate d from theburners may be attained, with the result that the oven will be heateduniformly, thus insuring superior results in the use of said oven.

, It is obvious that the construction which I have described is such asto admit of my improved oven being produced at a reasonable cost ofmanufacture and that the same will be of great utility.

Having now fully described my invention,

A what I claim, and desire to secure by Letters purpose specilied.
